“…In Europe, the PEAGRO crop simulation model identified pea's greater sensitivity to weather changes compared with wheat and maize, and weather changes impacted pea yield more than soil factors (Mathe-Gaspar et al 2005). Given that pea breeding programs in Europe have identified that pea needs targeted breeding for its sensitivity to climatic variation (Annicchiarico and Iannucci 2008), the impact of climate in western Canada on spring pea needs to be addressed because its even shorter reproductive period is expected to further increase yield sensitivity to adverse temperature.…”

. 2015. Effect of heat and precipitation on pea yield and reproductive performance in the field. Can. J. Plant Sci. 95: 629Á639. Pea (Pisum sativum L.) is important globally as a cool season crop. Pea cultivars are heat-sensitive so our goal was to investigate how weather impacted growth and yield in recent cultivars in the Co-operative pea yield trials (2000 to 2009) for a dryland (Saskatoon) and an irrigated (Outlook) location. We explored relationships between days to maturity, days spent in reproductive growth (flowering to maturity), yield and various weather factors. Yield and the length of reproductive growth increased with seasonal precipitation. Pea was sensitive to heat but heat units did not satisfactorily describe growth and yield in all environments. Strong relationships were observed between crop growth and mean maximum daily temperature experienced during reproductive growth, and between crop growth and mean minimum temperature. The greater the mean maximum temperature (25.58C), the fewer the number of days (B35) spent in reproductive growth at the dryland location. At Outlook, 35 to 40 d in reproductive growth occurred in a much wider temperature range from 24.5 to 278C, and irrigation mitigated some reduction in yield. For dryland pea, more than 20 d in the season above 288C were associated with less time in reproductive growth and less yield. The threshold maximum temperature for yield reduction in the field was closer to 288C than 328C from published studies, and above 17.58C mean seasonal daily temperature. Western Canadian cultivars currently have short lifecycles, which make them heat sensitive. Heat tolerance could be improved by earlier flowering and a longer duration of flowering via an indeterminate habit. Future research will investigate pea nodal development, flowering and abortion patterns in a range of pea cultivars in field conditions.

Effets de la chaleur et des pre´cipitations sur le rendement du pois et sa performance a`la reproduction au champ. Can. J. Plant Sci. 95: 629Á639. Le pois (Pisum sativum L.) est une importante culture de saison froide dans le monde. Les varie´te´s de cette espe`ce e´tant sensibles a`la chaleur, les auteurs voulaient de´terminer l'impact des conditions me´te´orologiques sur la croissance et le rendement des plus re´cents cultivars pre´sente´s lors des essais coope´ratifs de 2000 a`2009 en milieu aride (Saskatoon) et sous irrigation (Outlook). À cette fin, ils ont examine´les liens entre le nombre de jours avant maturite´, la dure´e en jours de la croissance reproductive (de la floraison a`la maturite´), le rendement et plusieurs parame`tres climatiques. Le rendement et la dure´e de la croissance reproductive augmentent avec les pre´cipitations saisonnie`res. Bien que le pois soit sensible a`la chaleur, le nombre de degre´s-jours ne de´crit pas de manie`re satisfaisante sa croissance et son rendement dans tous les en...

“…Yields of miscanthus reported for trials all over Europe showed huge differences in biomass yields from 2 to 44 t × ha -1 [18]. In the opinion of M a t h e -G a s p a r et al [35], the growth and yielding of miscanthus and other crops in a given habitat are controlled by the soil and weather conditions as the main environmental factors.…”

A b s t r a c tAn important issue related to the cultivation of plants for energy purposes and poorly recognized so far is their impact on the environment, including biodiversity. The aim of the work was to assess weed flora diversity, canopy structure and yield of miscanthus cultivated on two types of soil: light and heavy.The The results showed that weed species diversity in a miscanthus crop was dependent on soil type. A larger number of weed species was found in miscanthus cultivated on heavy soil -37 -in comparison with miscanthus cultivated on light soil -33. Sorensen's indicators showed low similarity between weed communities in miscanthus on light and heavy soil. Weed abundance and percentage of weed cover were lower in miscanthus cultivated on light soil. Weed density decreased during the vegetation season as a result of increasing competitiveness of the miscanthus canopy against weeds. Miscanthus yields were more dependent on weather conditions than the type of soil. Plant height and shoot diameter as well as leaf area index (LAI) were higher in miscanthus grown on heavy soil.

“…The 4M model has been applied in previous studies focusing on soil and weather infl uence (Máthé-Gáspár et al, 2005), and on the effects of climate change on crop yields in Hungary (Fodor and Pásztor, 2010;Fodor et al, 2014). However, these studies are based mainly on experimental and non-representative farm-level data, whereas in this study we apply the model to representative Hungarian Farm Accountancy Data Network (FADN) data.…”
